William LeoGrande and Peter Kornbluh (2015) Back Channel to Cuba: The Hidden History of Negotiations between Washington and Havana.
This study provides a comprehensive, detailed account of diplomatic efforts, since the 1960s, to normalize bilateral relations. It includes a section on the run up and process that led to the December 2014 announcement. The book identifies the key variables that impeded normalization, while providing an account of some of the more interesting secret negotiations.
